• Dry condition
Conditions corresponding with service class 1 according to en 1995-1-1 are characterized by a moisture content in structural materials, which corresponds to the temperature of 20 °C and relative humidity of the ambient air of 65% few weeks a year at the most. most coniferous wood has the average moisture content not exceeding 12%.
• Humid condition
Conditions corresponding with service class 2 according to en 1995-1-1 are characterized by a moisture content in structural ma- terials, which corresponds to the temperature of 20 °C and relative humidity of the ambient air exceeding 85% few weeks a year at the most. most coniferous wood has the average moisture content not exceeding 20%.
• External condition
Conditions corresponding with service class 3 according to en 1995-1-1 is characterized by climatic conditions leading to higher moisture content than the second service class.
• Load-bearing (structural) use
Using the board under load as part of the building or other con- struction.
• Structural floor decking
Floor set of wood-based boards placed on joists and over- lapping its span. the boards under load freely deflect between the joists.
• Structural wall sheathing
Wood-based boards capable of providing mechanical strength for the wall construction.
• Structural roof decking
A set of wood-based boards placed on the rafters and over- lapping their span. the boards under load deflect freely be- tween the rafters.
